Main Features

Accurate linear and temperature compensation techniques to avoid testing errors caused by temperature changes;
Suitable for testing various non-conductive liquids; No need to calibrate based on the test liquid;
The range can be customized according to customer needs, and the flange structure can be customized;
No need to calibrate for the detection liquid, one calibration can be applied to the detection of different liquids;
Solved the disadvantage of capacitive liquid level sensors being easily affected by temperature;
Suitable for liquid level measurement in high-temperature fields.

Overview

By adopting the principle of dual capacitor self compensation, the traditional capacitive liquid level sensor is easily affected by temperature and medium, which improves the detection accuracy and stability of the sensor. It achieves high-precision measurement of liquid level under temperature and medium changes.
No need to calibrate based on the test liquid!
The capacitive liquid level transmitter adopts a coaxial capacitor, which consists of two coaxial cylindrical plates with inner and outer electrodes. When the liquid enters the container, it causes a change in the capacitance value between the sensor housing (outer electrode) and the sensing electrode (inner electrode), and outputs a liquid level signal, suitable for measuring various liquids.
